SA'WING APPARATUS.

Application filed July 6,

T all whom it Be it known may concern.

that l, JOHN TORLINSKI, a citizen of the United States, residing atNanticoke, in the county of Luzerne an State of Pennsylvania, haveinvented certain new and useful Improvements in Sawin Apparatus, ofwhich the following is a full, clear, and exact description.

The present invention relates to saws of the circular type, and has forits object to provide a saw of this type which may be either hand orpower operated and which may, at the same time, be oscillated in asuitable guide provided for that purpose.

A further object of the invention resides in the provision of aplurality of adjust ments whereby the saw may not only be raised orlowered, but also may be set at various angles in either a horizontalorvertical plane, as may be required to obtain the desired result.

Other objects and advantages of the invention will be apparent from thefollowing description when taken in connection with the accompanyingdrawings, in which:

Figure 1 is'a perspective view of the device detached from the worktable.

Figure 2 is an end view of the apparatus attached to a table and showingin dotted lines an adjustment of the saw at an angle to the vertical.

Figure 3 is an end view of the apparatus in the opposite direction tothat shown in Figure 2.

Figure & is a horizontal section taken on line -ll of Figure 3.

Figure 5 is a plan view of the device, showing in dotted lines anadjustment of the same in horizontal plane.

Figure 6 is a fragmentary section taken on line 6-6 of Figure 5 andlooking in the direction of the arrows.

Figure 7 is a fragmentary section taken on line 7-7 of Figure 5, and

Figure 8 is a front elevation of an attachment for use with theapparatus.

Referring to the drawings more in detail, the numeral 1 refers to atable or other suitable base structure on which my apparatus, indicatedgenerally by the numeral 2 is adapted to be secured by means of theclamp 3 and set-screw 4:.

Slidably mounted in the clamp 3 is a toothed standard or support 5 whichmay be vertically adjusted through the medium of a pinion 5' and lockedin adjusted position Serial No. 649,944.

by set-screw 6. A bracket 7 is rotatably mounted in the upper end of thesupport 5 by means of the pintle 8, as clearly shown in Figure 7 and aset-screw 7 is provided for normally preventing rotation of the pintle.The bracket 7 forms a support for the rectangular frame 9 provided withguideways 10; the frame being pivotally connected to the bracket 7 bymeans of the p intle 11 indicated in Figure 7 r In the present instancea circular saw '12 is the cutting instrument, and is secured to shaft18, the latter belng suitably operated;

by the gear train 14. The gears i l and shaft 13 are preferably mountedin a casing 15 formed'for co-operation with the guideways 10, andprovided with a contr'o khandle 16. ll hile'a handle 17 is disclosed foroperating the saw 12, it will be understood that any kind of power maybe substituted therefor.

For the purpose of adjusting the frame 9 and likewise the saw 12 atvarying angles in a horizontal plane I have provided the slottedsegment. or gauge 18 which is suitably graduated as designated bynumeral 19. This segment is carried by the lower end of a rod 20 whichis adjustably mounted in bracket 7 by means of the set-screw 21. Theframe may be locked in its varying horizontal positions by set-screw 22which ex ends through the slot of segment 18 and is threaded into clamp3.

it is also found desirable to alter the vertical angle of the saw. andto this end the bracket 7 is formed with a slotted segment 23, alsosuitably graduated, which receives an extension 24 of the frame 9. Theextension 2% is suitably threaded for the reception of a nut 23 wherebythe frame is locked in the desired adjusted position.

In order that the frame 9 may be firmly supported at the end remote fromthe bracket 7, the same is provided with a sleeve 26 in which is mountedfor sliding movement a standard or leg 27 and which is adjustably lockedby means of the setscrew 28. The leg 27 has pivoted at its upper end asecond leg or standard 29 which is slotted for the reception of thecurved arm 30 also carried by the leg 27. A set-screw 31 is carried byleg 29, and through engagement with arm 30 will securel lock the legs intheir adjusted relative positions. From this construct on of the legs 27and 29 it will be obvious that as the frame 9 is moved to difierentvertical adjustments the leg 29 may be moved to a suitable position toco-operate with leg in supporting the end of the frame, as clearlyindicated in dotted lines in Figure 2.

In Figure 8 I have shown an attachment by means of which the saw 12 maybe adjusted along its axis for the purpose of ripping wood or otherpurposes. To this end the shaft 13 is threaded as indicated the guiderail 42 by means of a set-screw 43. The guide rail may be bolted to thecasing 15 through the medium of plate 44 and bolt holes 45, indicated inFigure l. The gear wheel 14 will, of course, be main tained in mesh withthe gear train by means of lock nuts 46.

In operation, if it is desired to place a bevel on a piece of lumber,the set-screw 6 is loosened to permit a proper vertical adjustment ofthe support 5, the segment 18 and rod 20 being allowed to remain intheir normal position relative to clamp 3 by loosening the set-screw 21and allowing bracket 7 to slide on rod 20. The nut 25 being loosened,the frame 9 may now be moved on its pivot 11 to the desired angle to thevertical, as indicated by graduations on segment 23, and the nut againtightened. Power now being applied to the crank handle 17, the operator,through manipulation of the handle 16, may apply the bevel to the pieceof lumber and may continue to apply the identical bevel to similarpieces of lumber so long as the adjustments remain the same.

Where it is desired to cut lumber at a certain angle in a horizontalplane it is only necessary loosen the amount of movement.

It will also be understood, of course, that certain designs in thewood-sawing art will require an adjustment of the saw in both a verticaland a horizontal plane, and such a position of the saw may be achievedby a combination of the adjustments just described.

From the foregoing description taken in connection with the accompanyingdrawings it will be seen that I have provided a durable andcomparatively simple woodsawing machine in which the saw is practicallyuniversally adjustable and in which accurate adjustments may be quicklyand easily accomplished.

In accordance with the patent statutes, I have described what I nowbelieve to be the best embodiment of the invention, but I do not wish tobe understood thereby as limiting myself or the scope of the invention,as many changes and modifications may be made without departing from thespirit of the invention, all such I aim to in clude in the scope of theappended claims.

What I claim as new and desire to secure by Letters Patent is:

1. A sawing mechanism, including a fixed element, a verticallyadjustable support connected thereto, a bracket Vrotatably mounted inthe upper end of the support, a frame pivoted to said bracket, means forlocking said frame in various adjusted positions on' its pivot, a gaugeslidably mounted in said bracket, means connecting the gauge to thefixed element, and a saw mounted for reciprocation in said frame.

2. A sawing mechanism, including a bracket, a frame provided withguideways pivoted to said bracket at one end of the frame, a circularsaw mounted for reciprocation in said guideways, and a pair of pivotallyconnected legs carried by the frame for supporting the opposite" endthereof in various adjusted positions.

3. A sawing mechanism, including a bracket, a frame provided withguideways pivoted to said bracket at one end of the frame, a circularsaw mounted for reciprocation in said guideways, a leg, means con nectmgsaid leg to the end of sald frame remote from its pivot, V j ting alongitudinal adjustmentof the leg with respect to the frame, a secondleg pivotally connected to the first-mentioned leg. and an adjustableconnection between said legs.
